I'm a little tired, but I wanted to put a couple of things up before I go to sleep. It is a subject I know little of (and I can't seem to go on for very long without wanting something new to research), the status of Mary with the Catholic Church.
A couple of things to look at:
Catachism - Mary- Mother of Christ, Mother of the Church
The Transitus Mariae
New to me, or maybe I had just forgotten. Anyway, I'll write later...
